Abstract: A width expanding device (100) comprises two rollers (1, 2, 3,) having complementary contours (15), e.g. helical contours, which mutually engage when the rollers (1, 2, 3) rotate. The product web (10) is taken through the expansion slot (12, 13) formed between the rollers (1, 2 or 1, 3) and is expanded in accordance with the depth of engagement of the contours (15) between two adjacent rises in the contours (5) across the width of the product web (10). The specific local width expansion is thus uniformly achieved over the entire width of the product web. The essential feature for the occurence of the effect is a pressure roller (7) adjacent to the expansion slots (12, 13) and bearing on the rollers (2, 3) which clamps the product web (10) between itself and the peaks of the reliefs (15) and secures it across its width.

Inventor: BATIC MARCO
IPC: B65D21/02
Filed: 1992-03-10
Abstract: A container arrangement comprises a plurality of stackable plastics containers (12) which have a container base (30) and four side walls (24, 26) which project above the container base, are connected to each other at rounded corners (22) and form a common upper rim (34).

Title: Bar=code arrangement for product marking and information - has multiple bar=code patterns each with different colours read using separate colour photodiode sensor
Inventor: KLOTZ ROLAND DIPL ING
IPC: G06K19/06
Filed: 1992-04-01
Abstract: The bar=code arrangement for indicating product and price details used multiple coding, each with a different colour. The bar code is formed with different width bars and in a conventional arrangement has a single colour. The same information content can be represented in a smaller surface area by housing multiple patterns in, for example, red, green and blue colours. Each colour bar code is read by a single photo diode. USE/ADVANTAGE - Reduces area required for bar=code, so allows more information to be represented in same area.

Abstract: PCT No. PCT/DE93/01022 Sec. 371 Date Jun. 7, 1995 Sec. 102(e) Date Jun. 7, 1995 PCT Filed Oct. 22, 1993 PCT Pub. No. WO94/13850 PCT Pub. Date Jun. 23, 1994A process and a device for coating the surface of strip material, especially non-ferrous metal and steel strip, with a metal coating, wherein the material is conducted without reversal of direction through a container holding the molten coating material. The container has a passage duct below the level of the melting bath, in which induction currents are induced by an electromagnetic travelling field and produce, in interaction with the electromagnetic travelling field, an electromagnetic force for restraining the coating material. In order to stabilize the melt in the passage duct as well as in the container, and in order to attain, to a large extent, a counterbalance between hydrostatic and electromagnetic forces, a constant direct or alternating current field is directed opposite to the travelling field in the area near the container, damping the movement in the coating material. For this purpose, an additional iron core, which has coils running parallel to the inductor coils and can be subjected to direct or alternating current, is arranged above each inductor on both sides of the passage duct.

Title: Paper layer system for the production of a postcard with or without copies, with turning-over and bonding of the text and address pages
Inventor: RADEBOLD CLAUS
IPC: B42D15/02
Filed: 1993-05-12
Abstract: In a postcard which is initially "folded open", the pages thus lying side by side, the front and back pages, are written upon. For the copy, a sheet of auto-reacting receptive carbon paper is used, this sheet having been fixed, by means of an adhesive bonding strip, on the back of the address page of the postcard. Instead of the carbon paper, a pull-off sheet of paper can be used to mask the adhesive bonding strip if a copy is not needed. After this paper or the carbon paper has been pulled off, the text page is bonded in reverse to the address page, using the adhesive bonding strip, and the postcard has now been produced.
